CVE-2026-82225 Overview
CVE-2026-82225 is a broken authentication vulnerability affecting the RegistrationMagic WordPress plugin in versions up to and including 6.0.9.8. The flaw allows unauthenticated attackers to bypass authentication controls over the network without user interaction. The weakness is categorized under CWE-288: Authentication Bypass Using an Alternate Path or Channel. Successful exploitation compromises the confidentiality and integrity of affected sites, potentially exposing user data and enabling unauthorized account access. The vulnerability was disclosed through Patchstack's WordPress vulnerability database.

Technical Details for CVE-2026-82225
Vulnerability Analysis
The RegistrationMagic plugin provides custom registration forms and submission management for WordPress sites. The affected versions contain a broken authentication flaw that permits attackers to circumvent the plugin's authentication logic. Because the plugin handles user registration and login workflows, a bypass in this component grants access that would otherwise require valid credentials.
The attack is remotely exploitable over the network and requires no privileges or user interaction. Attack complexity is elevated, indicating the attacker must satisfy conditions outside their direct control to reliably trigger the flaw.
Root Cause
The root cause aligns with CWE-288, where the application exposes an alternate authentication path or channel that does not enforce the same identity verification checks as the primary authentication flow. Attackers reach protected functionality without presenting valid credentials. Full technical specifics are documented in the Patchstack Vulnerability Report.
Attack Vector
An unauthenticated remote attacker sends crafted HTTP requests to the vulnerable WordPress endpoint exposed by the plugin. The requests exercise the alternate authentication path to obtain access to protected user or administrative context. No credentials, session tokens, or user interaction are required to initiate the attack.
No verified proof-of-concept code has been published. See the Patchstack Vulnerability Report for advisory details.
Detection Methods for CVE-2026-82225
Indicators of Compromise
- Unexpected successful logins or account state changes originating from unfamiliar IP addresses targeting RegistrationMagic endpoints
- Anomalous HTTP POST or GET requests to wp-admin/admin-ajax.php or plugin-specific routes tied to registration and login handlers
- Creation of new WordPress user accounts, especially with elevated roles, without corresponding administrator action
Detection Strategies
- Inventory WordPress installations and identify sites running RegistrationMagic at version 6.0.9.8 or earlier
- Review WordPress access logs for repeated requests to plugin authentication endpoints from single source IPs
- Correlate authentication events with plugin request patterns to identify sessions established without a valid login sequence
Monitoring Recommendations
- Enable verbose logging on the WordPress site and forward events to a centralized logging platform for retention and correlation
- Alert on new user registrations that receive administrative or editor roles outside of change-controlled processes
- Monitor for surges in traffic to /wp-content/plugins/custom-registration-form-builder-with-submission-manager/ paths
How to Mitigate CVE-2026-82225
Immediate Actions Required
- Update RegistrationMagic to a version later than 6.0.9.8 as soon as the vendor patch is available
- Audit all WordPress user accounts and remove any unauthorized users or unexpected role elevations
- Rotate credentials and force password resets for administrative accounts if compromise is suspected
Patch Information
Users should upgrade RegistrationMagic to a fixed release beyond version 6.0.9.8. Refer to the Patchstack Vulnerability Report for the fixed version and vendor guidance.
Workarounds
- Deactivate the RegistrationMagic plugin until a patched version can be installed if immediate updates are not possible
- Restrict access to WordPress registration and login endpoints using a web application firewall with rules targeting broken authentication patterns
- Enforce multi-factor authentication on all WordPress administrator accounts to reduce the impact of an authentication bypass
